WorkHero is building the AI-powered back office for the skilled trades, starting with the $50B+ HVAC industry. Small contractors are great at their trade but lose 20+ hours a week to invoicing, permits, scheduling, and paperwork. WorkHero combines expert office managers with automation and AI tooling, enabling a small team to take real ownership of that back-office work.

We’re hiring a senior full-stack engineer to build the product experiences and AI systems at the core of WorkHero—from React and React Native workflows to Node services, tool-using agents, and human-review loops. You’ll own systems end to end alongside a small, senior team with deep experience in AI, product, and the trades.

What you’ll build

You'll work across the product surface and the AI infrastructure behind it. For example:

New product screens and flows (jobs, customers, invoices, scheduling) in React and React Native, especially AI chat UI (chat & tool result rendering, streaming responses, human review and feedback loops)
AI workflows in production: tool-using agents, RAG/search, classification/extraction, and human-in-the-loop flows
Automations: Contribute new features and improvements to our AI-powered business automation platform
Integrations & ingestion: pull data from third-party systems (APIs/webhooks/files)
Evals & monitoring: regression tests for prompts/workflows, quality metrics, drift detection, and cost/latency tracking
Scalable systems: queues and orchestration, retries, data modeling, and API design to support rapid product iteration
UX polish and reliability improvements (loading states, edge cases, accessibility, performance)

Responsibilities

Analyze requirements and propose innovative AI-native solutions to technical problems
Write clean scalable code
Ship full-stack features across React, React Native (frontend) and Node (API/services)
Test and deploy features & services, and optimize the performance of our AI systems
Respond to critical system issues and ensure continuous system reliability
Mentor team members and collaborate across teams, especially with product and subject matter experts
Work to understand the needs of our users and think creatively about how to solve design challenges in your work
This is a Remote role. We expect Minimum 4 hours overlap with WorkHero team (11am-3pm ET).

Qualifications

Experience building and shipping production full-stack systems that you've owned
Strong React fundamentals (or equivalent modern frontend framework experience); React Native a plus
Strong Node.js backend fundamentals (REST and/or GraphQL) in a typed language (TypeScript preferred), plus comfort working across the stack
Hands-on experience with LLM-powered features (usage, prompting, optimization, etc), AI frameworks (Langchain, etc), and AI architectures (RAG, reranking, etc)
Experience building applications on modern databases (MongoDB, Postgres, or equivalent)
The ability to work with infrastructure as code (terraform), cloud, and CI/CD systems. We're a small team, so we own the whole stack!
Excitement to leverage AI coding tools to their maximum benefit. We love Claude Code and Cursor and are constantly looking for better ways to leverage our time to build fast and build for scale.

Nice to have

experience with audio streaming and/or building AI voice features
experience with workflow automation tools like n8n or Lindy
experience with HVAC or back-office business workflows
experience with mobile dev, especially Expo and/or React Native
experience specifically with AWS and how to get the most out of key AWS services

WorkHero is committed to building a diverse team. We encourage candidates from all backgrounds to apply.

Questions you could be asked

How would you design a retrieval step so the model answers from real data instead of guessing?
Walk me through how you've used Claude in your day-to-day work.
What are the limits of LangChain that you've run into, and how did you work around them?
What's a project where you used N8n hands-on?
Walk me through how you've used Cursor in your day-to-day work.

Adapt your resume

List these exact terms on your resume: Rag, Claude, LangChain, N8n, and Cursor. An applicant tracking system matches the wording, not the idea.
Attach one line of real, concrete experience to at least one of them — a tool named with nothing behind it rarely survives a human read.
Put the AI tool in a bullet point about what you did, not just in a skills list — this role treats it as a required part of the job.
